Virgin is offering three plan options, which both come with unlimited data and text messages. For $30 after discount you'll get 300 minutes for talk time. For $40 you'll get 1200 minutes, and for $50, you'll have unlimited minutes to talk to your heart's content. For an additional $15 a month, you'll be able to tether your iPhone to you computer and use it as a hotspot.

Even though you don't get contract pricing on the phone itself—Virgin will be selling the 16GB iPhone 4S for $650 and the 8GB iPhone 4 for $550—it's still an incredible deal that can save you buckets of cash: At least $500 over two years if you're using Sprint, AT&T, or Verizon. Check out this handy chart produced by Cult of Mac. If you sign up for Virgin's $40 per month plan you'll pay only $1610 for two years compared to $2400 (AT&T and Verizon) and $2120 (Sprint).
